Preparation and Characterization of MnO2/Zeolite-Y Nanoporous and Its Application as an Efficient Catalyst in the Three-Component Synthesis of Ethyl Benzimidazolyl-2-Aminothio Acetate under Green Conditions
In the present study, with the knowledge of the properties and advantages of various nano-porous materials, nanoparticles of manganese oxide (II) were exchanged on the zeolite-Y surface (covalent bond) and its structure was characterized by using various techniques such as FT-IR, XRD, BET, FESEM, and EDX analyses. In the following, the manganese oxide/zeolite (MnO2@zeolite-Y) as a green active nanocatalyst for the synthesis of ethyl 2-((1H-benzo[d]imidazole-2-ylamine)(ariyl)methylthio) acetate were used via a one-pot multicomponent reaction of aryl aldehydes, 2-amino benzimidazole, and ethyl 2-mercaptoacetate in a water-ethanol solvent and room temperature. This catalytic method has many advantages, such as the use of non-toxic, low-cost, available, and recyclable acidic nanocatalyst (Lewis), the short reaction time, the ease of separating pure products, the use of green solvents, and mild conditions. The present method also promises that in the future it can be used as a convenient synthetic route for the preparation of new sulfur-bearing peptide derivatives based on 2-amino benzimidazole core under moderate conditions.
